It is an integer and a rational number
1. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd
a^2b^2+8ab−9ab−72
2. Collect the like terms
a^2b^2+(8ab−9ab)−72
3. Simplify
a^2b^2-ab-72
Hope this helps
Answer:
Step-by-step explanation:
Given
Required
Determine the coordinates of L
Since T is the midpoint of K and L, we make use of:
and
Solving for 
Multiply through by 2
Solving for 
Multiply through by 2
Hence: The coordinates of L is:
2x + x - 1 x
= ------------------ * ---------
x(x - 1) 8
3x - 1
= --------------
8x - 8
The ratio of 186:76 can be simplified to 93:38 if we divide both numbers by 2.
